There are differences of opinion about how to determine the dates of the beginning of the year and the dates of the Lord’s commanded to keep holy days (for His set apart people). I’ve studied and, for now at least, this way of Scriptural understanding is what i believe. However, the dates (not the holy days) should not be a divisive issue.
How to calculate the calendar.
1) A year begins at the first new moon after the vernal equinox.
2) A month starts at the sundown after the lunar conjunction.

Whether you began Sukkot yesterday evening or this evening, whether you follow one of the Jewish calendars, or set your calendar by the siting of the moon, we all are seeking to honor and worship our Heavenly Father on His set-apart, holy days – His Feasts, seasons, – His moadim. As the fullness of time continues, perhaps the knowledge will be so that we all celebrate together. However, when the King of Kings returns to set up His Kingdom, we will be of one accord in singing the praises of the one true YHWH on His Appointed times. Praise Yah, the Messiah and Redeemer, Who takes away the sin of the world.
